A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.
